The heavy duty housing in stainless steel, AISI 36, is specifi cally designed for applications in corrosive environments and medias. FlexBar 350 measures the pressure by means of a ceramic, capacitive sensor. The measuring sensor and the electronics are in a separate chamber eliminating the risk of pressure and media in the terminal chamber. FlexBar 350 is confi gurable either with a handheld HART communicator or with the dedicated FlexProgrammer confi guring tool connected to a PC. On-site adjustment of span and zero point can be made in hazardous zones with 4 push buttons on the transmitter. The HART communication features on-line process calibration/ adjustment and transmitter confi guration. FlexBar 350 is used in chemical and petrochemical industries as well as in power plants and pulp and paper production. If mounted with one of the hygienic connections, with fl ush mounted ceramic measuring cell, the FlexBar 350 is the ideal pressure transmitter within harsh environmental measuring applications in the food-, beverage and pharmaceutical industry.

Device address: 0 FlexBar 350 is available with 7 different integrated process connections and with seals according to the customers wishes. The housing is 70 rotatable in respect to the process connection. The O-ring sealing between the process connection and the sensor is available in 3 types matching different medias. Accessories for FlexBar 350 are usually supplied separately and must be assembled by the customer. Having the HART communication facilities the FlexBar 350 can be operated as a conventional ma device, or it can be connected to other HART devices in a -wire HART network, in one of three connection methods: Mixed-signal mode, Point-to-Point mode or Multidrop mode. Please refer to HART literature. The integrated 4-digit LC-display is optional. Terms Overview Output (ma) Down scale limits Up scale limits Output limits Linear output Nominal output Transfer curve.
